Fedora 32 and github pages

Last week I’ve updated my working machine to Fedora 32. Upgrade went smoothly and, after a week, I thought that I wouldn’t face any issues.

However, when today I tried to write a new post to my blog, following error appeared:

[sab@fz sbulav.github.io] (master *%)$ make serve
bundle exec jekyll serve -H 0.0.0.0 --watch --port 8080 --livereload
bundler: failed to load command: jekyll (/usr/bin/jekyll)
LoadError: libruby.so.2.6: cannot open shared object file: No such file or directory - /usr/lib64/gems/ruby/nokogiri-1.10.9/nokogiri/nokogiri.so
...

The file was clearly there and all the permissions were in place. After couple hours of investigation, following things became clear:

• Fedora 32 uses Ruby 2.7 as default
• At the time of writing, gem nokogiri don’t fully support Ruby 2.7
• Github pages don’t support Jekyll 4+

So the decision was to install Ruby 2.6 in Fedora 32 using rvm.

Here’s what I’ve used to install Ruby 2.6 and reinstall gems:

# Install rvm
curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -
curl -L get.rvm.io | bash -s stable

# Source environment
source ~/.rvm/scripts/rvm
rvm reload

# Install Ruby 2.6
rvm requirements run
rvm list known
rvm install 2.6

# Install bundler
gem install bundler:2.1.4

# Reinstall gems for blog
bundle
